Pairess

Pairess: noun. According to old French tradition, a pairess is a duo of females that get to inherit some sort of valuable item. This used to be quite useful during the twin epidemics of Paris in the early 1700s, when for some strange reason, people could only give birth to female twins. Pairessing was, therefore, a very easy way of bequeathing one's fortune evenly and without the necessity of finding male heirs, who were (at least before the introduction of this custom) driven in all the way from Marseilles.
